Microbiological analysis results showed more reduction in red-complex bacteria in the laser group compared to the SRP group, but they were statistically insignificant.
Within the limitation of this study, it is recommended that both the SRP and SRP + laser are effective in chronic periodontitis management, but using laser with SRP has propitious results. Thus, in the forthcoming years, clinical experiments with a greater sample size may be chosen to further analyze the fringe benefits of laser as a supplement to SRP.

The bone model had a cancellous core of (0.5?mm) which represents D4 bone. A 7.5x4.6?mm screw type implant system with 3.5 platform switch abutment was selected. ANSYS WORKBENCH was used to model all the finite element structures. Force of 100 N was tested and adapted at an angle of 0º, 15º, 30º on the tooth model. Overall results from the current study showed that a high amount of stress was seen in cortical than in relation to cancellous bone. Stress values reduced from equicrestal to subcrestal (2?mm) placement of dental implants irrespective of angulation of load from 0o to 30o in both types of bone. However higher stress values were seen when force was applied in an oblique direction (30o) in comparison to a vertical load (0o). Least amount of stress was noticed when platform switched implants were placed 0.5?mm subcrestatlly irrespective of angulations of a load. Platform switched short subcrestal implants reduced the stress in the D4 cortical bone than in contrary equicrestal implant placement. This results in the preservation of marginal bone leading to implant success.Dental caries is one of the commonest oral diseases that require early stages of prevention and intervention. The primary organisms related to dental caries are streptococcus mutans and lactobacilli. In the past decades, some of the non-pathogenic bacteria called probiotics have been added to the food products for the beneficial effect of human health. Intake of probiotic food products has been shown to have beneficial effects on the oral tissues. Hence the present study aimed to compare the levels of salivary pH, S. mutans, B. dentium counts in children consuming probiotic and non-probiotic curd.
40 healthy caries free children were randomly allocated into two groups. First baseline salivary samples were collected from all the participants and tested for salivary pH, salivary B. dentium and S. mutans count. After collecting the baseline values test group of children were provided with probiotic curd whereas the control group were provided with non probiotic curd for 15 days. After 15 days of consumption of these dairy products, salivary samples were collected again and tested for salivary pH, salivary B. dentium and S. mutans count.
Probiotic curd was found to be more effective in reducing the colony counts of B.dentium and S.mutans. There was a marginal decrease in pH in both the groups but was well above the critical pH.
Probiotic curd showed considerable level of decrease in colony counts of B.dentium, S.mutans and salivary pH when compared to normal curd.

Fiber-reinforced composite and other commercially available bulkfill composites were used. Fifteen cylindrical specimens (5?mm × 5?mm) were made from each material in metal template. Molds were filled in one increment for both bulkfill composites and fiber-reinforced composite and cured using Ivoclar blue phase light-curing unit at a wavelength of 850 mW/cm. A dark container was used to store specimens to keep dry at room temperature for 24?h before testing. Vickers hardness number (VHN) on the top and bottom surfaces of each specimen was measured by a microhardness tester. Data for VHN were analyzed by using analysis of variance (ANOVA) and pair-wise Newman-Keuls test.
No significant difference was observed in Vickers hardness test. The mean value of VHN on the top and bottom surfaces showed significant difference from each other. Fiber-reinforced composite showed the highest VHN as compared with other materials.
Fiber-reinforced composite has the highest Vickers hardness ratio indicating highest degree of conversion and better clinical performance.

However, bioactivity studies focusing on the ability of sandblasting and ultraviolet photofunctionalization (UVP) surface treatments in inducing apatite precipitation using simulated body fluid (SBF) are lacking.
The aim of the study was to comparatively evaluate the effect of two different surface treatments-sandblasting with 50 ?m alumina and UVP with ultraviolet C (UVC) light on the bioactivity of zirconia.
A total of 33 discs with dimensions 10?mm × 2?mm were obtained from zirconia blanks (Amann Girrbach, Koblach, Austria) and randomly divided into three groups (= 11), namely Group I (untreated), Group II (sandblasted), and Group III (UVP). Surface characteristics of representative test samples were analyzed using X-ray diffraction (XRD), atomic force microscopy (AFM), contact angle goniometry, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX), to assess type of crystal phase of zirconia, surface roughness, wettability, surface topography, and elemental composition, respectively.
